So I re-ordered all of the exhaust tubing in mild steel. I kept the stainless collector, muffler, and v-band clamps.

I added a heat shield to the fuel line coming up near the firewall. I also flipped the fuel rail which allows me to run the fuel line up the back of the firewall over the transmission. It also gives a little more room between it and the exhaust.

Replaced the LS6 IM gaskets

Ready to go:

Installed. I'm just going to use the stock fuel rail and LS6 injectors. It will run, but i'll need to send the ECU back in for tuning. I also need to order some injector wiring adapters.

Where did you source the v-band clamps? I'm looking into converting my setup to them as well when I build my next exhaust (which has become a much higher priority now that I found I have half a muffler in my XJ).

I am rehabbing my old 90, and I want to get away from the band clamps and 3-hole flanges I used there. One thing I should point out in case you haven't come across this- when welding the clamps (any clamp but apparently the v-bands especially like to walk on you), have them mated up when you are welding. Of course, vary your welding as well- weld a little here, then a little on the other side, then let it cool. Come back and connect the dots till she's sealed up.

This will give you the best shot at maintaining a sealed flange when you final assemble everything. If you just weld the v-band halves onto the pipes and then try to joint them up you will quite likely find they have deformed to the extent they no longer will seal. There's also something called a Marmon flange .. which I just happily found on Amazon!

I haven't used these yet, but they are supposed to be MUCH more forgiving with welding, and they actually seal on a fiber gasket as opposed to a machined surface. I wouldn't buy them there, though. $24 shipping, and it isn't even a complete assembly. I'll try to find a much better source I saw a few months ago...

I've also run into a small road block. Got the intake all installed and got the correct injector adapters installed.

The Jeep wont start now. I hadn't started it in a while but it did run and they only thing that changed was the intake. Unfortunately the computer isnt spitting out any codes either.

Could the mismatched injectors in the tune cause it not to start?

I’m also thinking of starting this swap process with a new shell. I’d like to use a <‘93, with manual windows and locks. Using an older Jeep would allow me to register it as a classic and not worry about SMOG. My Jeep also has a registration restriction under my name. (Long story is that I canceled insurance and never turned in the plates so according to the dmv I was driving without insurance. $1200 fine and need to carry special insurance.). I can get around this by registering under a different name or getting a new Jeep.
